AI Technical Summary

Problems solved by technology

[0003] In the production of aluminum powder paste (also called aluminum silver paste, aluminum pigment, commonly known in the industry), it is often necessary to use a ball mill to grind the aluminum powder paste to a certain particle size before it can be used in the production of metal paint; the existing aluminum powder paste In the production process, there are many defects: firstly, equipment defects, and secondly, there are process defects

[0004] The defect of the equipment is that most of the existing ball mills are horizontally supported by the bearing seats at both ends of the ball mill, and due to the relationship between the incoming and outgoing materials, the shaft rods mostly use hollow shaft tubes. In actual use, due to the long-term influence of gravity, the hollow shaft The bending degree of the tube is becoming more and more serious. When the ball mill is running and rotating, the coaxiality ratio will drop greatly, which will affect the normal operation of the ball mill, and even cause damage to the ball mill in severe cases. In addition, when producing aluminum powder slurry, it needs to be milled by a ball mill. During the ball milling process, as the medium grinds the raw materials, a large amount of heat will be generated, resulting in an increase in the surface temperature of the ball mill and the temperature of the workshop, which is not conducive to the work of workers. Generally, the top spray method is used to cool down, but due to The contact area on the surface of the ball mill shell is not large, and the cooling effect is poor. Even if the amount of spraying water is increased, most of the water will be dripped and lost, resulting in waste of water resources; at the same time, there is a lack of necessary cooling measures when discharging, resulting in The surface of the high-temperature aluminum powder slurry is seriously oxidized during discharge, which affects the quality of the aluminum powder slurry produced

[0005] The process defect is that the particle size of the aluminum powder slurry after ball milling is quite different, and the necessary screening is lacking. If it is put into use, the quality of the metal paint will be greatly reduced, and the actual use effect of the metal paint will be affected.
